In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific examples. The following related technologies may be optionally combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the protection scope of the embodiments of the present application. The embodiment of the present application includes at least part of the following contents.

At present, with people's pursuit of speed, delay, high-speed mobility, and energy efficiency, as well as the diversity and complexity of business in future life, 5G communication networks have been introduced. The main application scenarios of 5G are: Enhanced Mobile Broadband (Enhance Mobile Broadband, eMBB), Ultra-Reliable and Low Latency Communication (URLLC), Massive machine type of communication (mMTC) ).

eMBB still aims at users' access to multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, and rural areas, the capabilities and requirements vary greatly, so it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, electric power automation, telemedicine operations (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive services, low cost and long service life of modules, etc.

NR can also be deployed independently. In order to reduce air interface signaling and quickly restore wireless connections and data services in the 5G network environment, a new RRC state is introduced, namely the RRC_INACTIVE state. The RRC_INACTIVE state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state.

RRC_IDLE: Mobility is terminal-based cell selection and reselection, paging is initiated by the core network (Core Network, CN), and the paging area is configured by the CN. There is no Access Stratum (AS) context of the terminal on the base station side. There is no RRC connection.

RRC_CONNECTED: There is an RRC connection, and the base station and the terminal have the AS context of the terminal. The network side knows the location of the terminal at the specific cell level. Mobility is mobility controlled by the network side. Unicast data can be transmitted between the terminal and the base station.

RRC_INACTIVE: Mobility is cell selection and reselection based on the terminal, there is a connection between the core network and NR (CN-NR), the AS context of the terminal exists on a certain base station, and paging is performed by the radio access network (Radio Access Network, RAN) trigger, the RAN-based paging area is managed by the RAN, and the network side knows the location of the terminal based on the RAN paging area level.

For a better understanding of the embodiments of the present application, the RRM measurement relaxation of the UE in the NR non-connected state related to the present application will be described.

To support relaxed neighbor cell measurements, the low mobility criterion and the not at cell edge criterion are introduced. Both sets of criteria are measured by the measurement results of the terminal equipment on the serving cell.

"low mobility" guidelines

For the "low mobility" criterion, the network will configure the evaluation time TSearchDeltaP of the reference signal received power (Reference Signal Received Power, RSRP) change and the RSRP change value threshold SSearchDeltaP. When the RSRP variation of the terminal equipment in the TSearchDeltaP on the serving cell is smaller than that of the SSearchDeltaP, the terminal equipment is considered to meet the "low mobility" criterion. That is: within a period of TSearchDeltaP, the following formula 1 is satisfied:

(SrxlevRef–Srxlev)<SSearchDeltaP Formula 1

Wherein, Srxlev is the current Srxlev (ie RSRP) measurement value of the serving cell, and SrxlevRef is a reference Srxlev (ie RSRP) value of the serving cell.

When the terminal device selects or reselects to a new cell, or if (Srxlev-SrxlevRef)>0, or if the terminal device does not satisfy formula 1 within the continuous TSearchDeltaP time, the terminal device sets SrxlevRef as the current value of the serving cell Srxlev measurements. After completing cell selection/reselection, the terminal equipment needs to perform normal RRM measurement within at least a period of TSearchDeltaP.

"not-at-cell-edge" guidelines

For the "not-at-cell-edge" criterion, the network will configure an RSRP threshold SSearchThresholdP, and can also configure a Reference Signal Received Quality (RSRQ) threshold SSearchThresholdQ, when the RSRP of the terminal device on the serving cell is greater than The RSRP threshold, and when the RSRQ threshold of the terminal device on the serving cell is greater than the RSRQ threshold when the network configures the RSRQ threshold, the terminal device is considered to meet the "not-at-cell-edge" criterion.

In some embodiments, the measurement relaxation mechanism of adjacent cells in the connected state is introduced for the Reduced Capability (Reduced Capability, RedCap) terminal to further meet the power saving requirements of the terminal. The connection state measurement relaxation is controlled by the network. The network can configure the low mobility criterion to the terminal device. When the terminal device meets the low mobility criterion, it will report to the network. Instructs the terminal device to perform neighbor cell measurement relaxation.

To facilitate a better understanding of the embodiments of the present application, the NTN related to the present application is described.

Non-terrestrial communication network (NTN) generally uses satellite communication to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's region. For example, general land communication cannot cover areas such as oceans, mountains, deserts, etc. that cannot be equipped with communication equipment or are not covered by communication due to sparse population. For satellite communication, due to a Satellites can cover a large area of the ground, and satellites can orbit the earth, so theoretically every corner of the earth can be covered by satellite communications. Secondly, satellite communication has great social value. Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these regions can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed regions and promoting development of these areas. Thirdly, the distance of satellite communication is long, and the cost of communication does not increase significantly with the increase of communication distance; finally, the stability of satellite communication is high, and it is not limited by natural disasters.

Communication satellites are divided into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, and high elliptical orbit satellites according to their orbital heights. (High Elliptical Orbit, HEO) satellites and so on.

The altitude range of low-orbit satellites is 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between users is generally less than 20ms. The maximum satellite visible time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirements for the transmission power of the user terminal are not high.

Satellites in geosynchronous orbit have an orbital altitude of 35786km and a period of 24 hours around the earth. The signal propagation delay of single-hop communication between users is generally 250ms.

In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. ground area.

In some embodiments, there are two types of satellites, one is a transparent payload satellite, and the other is a regenerative payload satellite. The satellite network architecture for transparent forwarding may be shown in FIG. 2 , and the satellite network architecture for regenerative forwarding may be shown in FIG. 3 . Among them, the feeder link refers to the wireless link between the satellite and the NTN gateway (usually located on the ground).

In order to better understand the embodiments of the present application, the problems solved in the present application will be described.

In the NR terrestrial network, the reference signal received power RSRP when the UE is at the center of the cell is significantly higher than that when it is at the edge of the cell. Due to the obvious "near and far effect", it can be judged based on the RSRP measurement whether the RRM measurement relaxation criterion is met, that is, if the network is configured with the not at cell edge criterion, the UE can judge whether it is a channel through the RSRP measurement of the serving cell. The state is good enough to start relaxed RRM measurement for neighboring cells; when the network configures the Low mobility/stationary criterion, the UE can judge whether it is in a low mobility or stationary state based on its RSRP variation on the serving cell, Thereby, relaxed RRM measurements can be initiated for neighboring cells.

In the NTN system, for the UE at the center of the cell and the UE at the edge of the cell, their corresponding RSRP differences are not obvious. If the current RSRP-based measurement is used to determine whether the UE meets the Low mobility/stationary criterion or/and not at cell The edge criterion, on the one hand, it is difficult for the network to set an appropriate RSRP threshold, on the other hand, due to errors in RSRP measurement, it is likely to cause the UE to perform inappropriate measurement operations. For example, when the network is configured with the not at cell edge criterion, for users in the center of the cell, due to the low measured RSRP, the relaxed RRM measurement for neighboring cells is not started, which increases unnecessary terminal power consumption; Due to the high measured RSRP, relaxed RRM measurement is started for neighboring cells, which may cause the network to fail to find and reselect a more suitable neighboring cell in time, thus affecting the experience of the terminal.

Based on the above problems, this application proposes a RRM measurement relaxation related scheme. The terminal device determines whether it meets the target criterion corresponding to the RRM measurement relaxation mechanism of the neighboring cell based on its location information, and the terminal device passes the indication information whether it meets the target criterion Report to the network to assist the network in deciding whether to perform relaxed RRM measurement for neighboring cells.

The technical scheme of the present application is described in detail below through specific examples.

FIG. 4 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG. 4 , the wireless communication method 200 may include at least part of the following content:

S210, the terminal device determines whether the target criterion is met according to its location information; wherein, the target criterion is a criterion corresponding to the RRM measurement relaxation mechanism of the neighboring cell;

S220. The terminal device sends first indication information to the network device, where the first indication information is used to indicate whether the terminal device meets the target criterion;

S230. The network device receives the first indication information sent by the terminal device;

S240, the network device determines whether to perform relaxed RRM measurement for neighboring cells according to the first indication information.

In the embodiment of this application, the terminal device determines whether the terminal device itself meets the target criterion according to its location information, and the terminal device reports whether it meets the target criterion to the network device through the first indication information, so as to assist the network device in deciding whether to execute Relaxed RRM measurement.

In the embodiment of the present application, the terminal device may be in the connected state, that is, the embodiment of the present application may be applied to the RRM measurement relaxation mechanism of the adjacent cell of the connected state terminal in the NTN scenario, so as to meet the power saving requirement of the connected state terminal.

In this embodiment of the present application, the adjacent cell RRM measurement relaxation mechanism specifically refers to: the network device configures the target criterion to the terminal device, and the terminal device reports whether it satisfies the target criterion to the network device through indication information, and the network device can combine the information reported by the terminal device Refer to the signal quality (such as RSRP measurement result and/or RSRQ measurement result), and the indication information for whether the terminal device satisfies the target criterion, to decide whether to instruct the terminal device to perform relaxed RRM measurement of neighboring cells.

In some embodiments, the first indication information may be transmitted through uplink control information (Uplink Control Information, UCI) or radio resource control (Radio Resource Control, RRC) signaling or media access control control element (Media Access Control Control Element, MAC CE), of course, it can also be sent through other uplink signaling, which is not limited in this application.

Specifically, for example, the first indication information may occupy one bit in signaling carrying the first indication information.

Optionally, the first indication information is used to indicate that the terminal device satisfies the target criterion, and the network device may determine whether to Instruct the terminal device to perform relaxed neighbor cell RRM measurement.

In some embodiments, when the first indication information indicates that the terminal device satisfies the target criterion, the network device determines to perform relaxed RRM measurement for neighboring cells; and/or, when the first indication information indicates that the terminal In the case that the device does not meet the target criterion, the network device determines not to perform relaxed RRM measurement for the neighboring cell.

In some embodiments, the target criterion includes a first criterion, or, the target criterion includes a first criterion and a second criterion, or, the target criterion includes a first criterion and/or a second criterion. For example, the first criterion and/or the second criterion is a low mobility criterion; or, the first criterion and/or the second criterion is a stationary criterion.

In some embodiments, the first criterion refers to: within the first time period, the amount of change in the distance from the terminal device to the reference point in the serving cell is smaller than a first threshold.

That is, for the first criterion, its evaluation duration may be the first duration.

Specifically, for example, the reference point may be the center point of the ground coverage of the satellite in the serving cell in the NTN system, or the reference point may be a point within a certain range around the center point of the ground coverage of the satellite in the serving cell in the NTN system. Applications are not limited to this.

Specifically, the terminal device may determine the amount of change in distance from the terminal device to the reference point based on the location information of the terminal device.

In some embodiments, the first criterion may also be referred to as a low mobility criterion or a static criterion based on the location of the terminal.

In some embodiments, the second criterion means: within the second duration, the difference between the reference signal quality reference value in the serving cell and the first reference signal quality measured by the terminal device on the serving cell is smaller than the second threshold limit.

That is, for the second criterion, its evaluation duration may be the second duration. For example, the second duration is TSearchDeltaP.

In some embodiments, the first reference signal quality may be one of the following: Reference Signal Received Power (Reference Signal Received Power, RSRP), Reference Signal Received Quality (Reference Signal Received Quality, RSRQ), Signal to Interference and Noise Ratio (Signal to Interference plus Noise Ratio, SINR), Reference Signal Carrier to Interference plus Noise Ratio (RS-SINR), Received Signal Strength Indication (RSSI).
